Abstract (en)
[origin: EP0321163A2] Argon and oxygen are separated from mixtures thereof, optionally with nitrogen, by cryogenic distillation in which liquid and vapor phase streams are intimately contacted using structured packing in at least those regions of the distillation column system where argon concentration is within the range from 0.6 to 75 volume percent, and operating the process such that the densimetric superficial gas velocity in those regions is at least 1.8 cm/sec.
